“…Rrecently, numerous studies have been conducted on the impact of inorganic pollutants such as heavy metals and nitrite ions on water quality [14][15][16][17][18][19][20]. Indeed, to detect these ions, different electrochemical sensors based on modified electrodes were developed [21][22][23][24][25][26][27][28][29][30].…”

Journal of Molecular Structure, Elsevier, 2014, 1076A new ternary ruthenium (III) complex with 1,3-bis (salicylideneamino) propan-2-ol and 3picolylamine: Synthesis, characterization, density functional theory and preparation of electrochemical sensor for nitrite analysis. AbstractA novel electrochemical sensor based on graphite (G) functionalised with a new ternary ruthenium (III) complex was developed and applied to detect nitrite in aqueous solution. The Ru (III) complex was synthesized using 1,3-bis(salicylideneamino) propan-2-ol polydentate Schiff base (BSAP) and 3-Picolylamine (PLA), and was characterized by elemental analysis, Fourier transform infrared spectroscopy (FT-IR), Ultraviolet-visible spectrophotometry (UV-Visible), gradient-assisted hetero nuclear single quantum coherence spectroscopy (gHSQC) and cyclic voltammetry technique. In addition, the structure of the synthesized complex was optimized using density functional theory (DFT). The results showed that the ternary Ru(III)-BSAP-PLA complex was formed and the adapted structure was an tetrahedral geometry.The electrochemical behavior of nitrite at the sensor prepared using G/Ru(III)-BSAP-PLA composite shows that the evaluated electron transfer coefficient ( 83 . 0 = α ) indicates a very significant electrocatalytic mechanism for oxidation of nitrite in the presence of the Ru(III)-BSAP-PLA complex.Comparing to other published works, the sensor developed using G/Ru(III)-BSAP-PLA exhibited low limit of detection ( LOD=1.81 µM) around pH=7. Highlights• Ternary ruthenium(III) complex with 1,3-bis(salicylideneamino) propan-2-ol polydentate base Schiff (BSAP) and 3-Picolylamine (PLA) was synthesized, characterized and the structure was optimized using density functional theory.• Graphite-Ru(III)-BSAP-PLA composite material was prepared and characterized by scanning electron microscopy coupled with energy dispersive spectroscopy (SEM-EDS).• Cavity microelectrode (CME) was modified with graphite-Ruthenium(III)-BSAP-PLA material.• Substantial electro catalytic effect of ruthenium(III)-BSAP-PLA complex on oxidation of nitrite was determined by using CME/G/Ru(III)-BSAP-PLA modified electrode.

“…Moreover, it also possesses thermal stability, chemical inertness, mechanical strength and antifouling properties [30][31][32][33][34][35]. Metal and metal oxide nanoparticles are also used as the electrode modifier because they possess extreme small particle size, high surface area, high surface-to-volume ratio and better catalytic activity [36][37][38][39]. Zirconia (ZrO 2 ) nanoparticles were used as the electrode modifier for the electrochemical sensing of organophosphorus pesticides since it has strong affinity towards the phosphoric group [40].…”

“…The results are displayed in Table 1 . Although the analytical performance of GO-CS-AuNPs/GCE is slightly weaker than these reported biosensors [ 2 , 22 , 24 , 30 , 31 , 32 ], the preparation process of GO-CS-AuNPs/GCE is relatively simple and the selectivity is high. Moreover, the detection limit of our proposed GO-CS-AuNPs/GCE is lower than other reported biosensors [ 33 , 34 , 35 , 36 , 37 , 38 ].…”

A highly sensitive nitrite (NO2−) electrochemical sensor is fabricated using glassy carbon electrode modified with Au nanoparticle and grapheme oxide. Briefly, this electrochemical sensor was prepared by drop-coating graphene oxide-chitosan mixed film on the surface of the electrode and then electrodepositing a layer of Au nanoparticle using cyclic voltammetry. The electrochemical behavior of NO2− on the sensor was investigated by cyclic voltammetry and amperometric i-t curve. The results showed that the sensor exhibited better electrocatalytic activity for NO2− in 0.1 mol/L phosphate buffer solution (PBS) (pH 5.0). The oxidation peak current was positively correlated with NO2− concentration in the ranges of 0.9 µM to 18.9 µM. The detection limit was estimated to be 0.3 µM. In addition, the interference of some common ions (e.g., NO3−, CO32−, SO42−, Cl−, Ca2+ and Mg2+) and oxidizable compound including sodium sulfite and ascorbic acid in the detection of nitrite was also studied. The results show that this sensor is more sensitive and selective to NO2−. Therefore, this electrochemical sensor provided an effective tool for the detection of NO2−.
